About AI Image Extender
The AI Image Extender adds new picture around the edges of a photo, so you can change its shape without cropping anything away. Turn a vertical phone shot into a 16:9 slide or video thumbnail, make a landscape photo fit a 9:16 story, or give a tightly framed product more breathing room. For marketplace main images, AI Product Photo puts the product on white with a margin you set.
Pick the Aspect ratio from 16:9, 9:16, 1:1 or 4:3. The AI continues the scene outward, extending sky, walls, floors, grass or backdrops so the new areas blend in. The added parts are invented, not recovered, so check faces, hands and text near the edges. Simple, even backgrounds extend most convincingly.
